ADVERTISING-MACHIN E.

Application filed July 15, 1920.

To all wkomz'tmag concern:

Be it known that 1, JOHN BROATCH, a subject of the King of Great Britain, and a city of Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Advertising-Machines, of which the following is a specification.

My invention relates to improvements in advertising machines, and the object of my invention is to provide a simply constructed, practical and eiiicient means whereby advertising matter may be displayed me chanically and in a highly novel and attractive manner.

I attain this object by the construction illustrated in the accompanying drawings in which Figure l is a front view of the machine.

Fig. 2 is an end view with one side removed. I

Fig. 3 is a sectional plan view taken on line 3-3 of Fig. 1.

- operated by a gear 9 secured to Similar figures of reference indicate similar parts throughout the several views.

1 indicates the casing of the machine within which are inclosed the several parts, and which is provided with a display opening 2, the edge of which may be flared outwardly as at 3, if desired. Positioned within the casing behind the opening 2 and of greater area than the same are advertising plates 4 on which the advertising matter is printed, there being seven such plates shown in the device illustrated in Fig. 2, although there may beany other desired number, and these plates are arranged one behind the other,

the innermost "plate being supported by vertical supporting members 5, formed preferably of angle iron, which are inclined slightly backwardly, there being one such member adjacent the ends of the sign plates. The upper ends of the members 5 are bent backwardly to form an inclined table or chute 6 on Which the respective plates fall when elevated, as hereinafter described. Each plate 4 is provided at midlength with a toothed rack 7 with the upper end of which a rotatably mounted gear 8 is adapted to normally engage, and which gear is the shaft 10 is mounted, the gear 9 being itself driven by a gear 11 secured to a suitably supported rotatable shaft 12 operated by a motor 13 with which it is conon which gear 8 Specification of Letters Patent.

Patented Mar. 15, 1921 Serial No. 396,357.

21 and 22 indicate sheaves rotatably mounted in the upper part of the casing 1 around which are passed cables 23 and 24 to the front ends of which is secured a curtain 25 which passes over a roller 39 and the lower edge of which is provided with an inwardly projecting ledge as indicated at 26 the under surface of which is beveled out wardly as at 27 while to the opposite ends of the cables are secured counterweights 28 and 29, the weight of which is such as will practically balance the curtain and maintain it with the ledge 26 he upper edge of the opening 2,

The lower end of the counterweight 28 is adapted to contact when in its lower position with a depressible electrical terminal 30 carried by a stationary support 31 within which is secured a stationary terminal 32, wires 33 and 34 of a suitable electrical circuit used for illuminating the machine being connected respectively to the terminals 30 and 32. The terminal 30 is resiliently supported by a spring 35 so as to be raised to its normal position to break the circuit when the counterweight rises.

36 indicates a stop member having an inclined face 37 against which the beveled surface 27 of the ledge contacts when the then causes theeurtain to drop ,and as soon as it commences to travel downwardly the electrical circuit 18 broken by the separajust slightly above tion of the terminal 30 from terminal 32 due to the rising of the counterweight so that the machine is in darkness while the curtain is dropping. On reaching the end of its travel the beveled surface 27 of the curtain ledge 26 contacts with the inclined face 37 of the stop 36 so that the ledge of the curtain passes into the opening 38 tilting it and allowing the plate to fall free, whereupon the curtain is then raised again by the counterweights, the illumination of the machine being again switched on when the counterweight 28 causes the terminal contact to be again made. The operation just described is continuous as long as the motor is in operation, each back plate being taken and moved mechanically to the front and as the changing of the plates takes place in the dark without any mechanism being visible the machine possesses great novelty and is highly attractive.

What I claim as my inventionis 1. An advertising machine comprising a casing having a display opening, a plurality of advertising cards stacked directly behind said opening with the front card exposed through the opening, and means for elevating the rearmost card of the stack and then guiding it forwardly and downwardly to an exposed position in advance of the remaining cards and opposite said opening. i

2. An advertising machine comprising a casing having a display aperture, a plurality of advertising plates arranged one behind the other behind said aperture, supports for said plates adapted to maintain them slightly inclined backwardly, a for wardly and downwardly inclined chute at the upper end of said supports, meansfor raising said plates one at a time to a height at ivhich they overbalance and fall on said chute, and a curtain hung above said aperture having a projecting ledge at its lower edge adapted to receive the lower edge of a plate as it drops from the chute, said ourtain being adapted to be then lowered by the weight of the said plate.

3. An advertisingmachine comprising a casing having a display aperture, a plurality of advertising plates arranged one behind the-othe-r behind said aperture, supports for said plates adapted to maintain them slightly inclined backwardly, a forwardly and downwardly inclined-chute at the upper end of said supports, means for' raising said plates one at a time to a height at which they overbalance and fall on said chute, acurtain hung above said aperture having a projecting ledge at its lower edge adapted to receive the lower edge of a plate as it drops from the chute, said curtain being. adapted to be then lowered by the weight of the said. plate, and means for free ing the plate from the curtain ledge when evine-1 the curtain reaches the termination of its downward travel.

4:. An advertising machine comprising a casing having a display aperture, a plurality of advertising plates arranged one behind the other behind said aperture, supports for said plates adapted to maintain them slightly inclined backwardly, a forwardly and downwardly inclined chute at the upper end of said supports, means for raising said plates one at a time to a height at which they overba-lance and fall on said chute, a curtain hung above said aperture having a projecting ledge at its lower edge adapted to. receive the lower edge of a plate as it drops from the chute, said curtain being adapted to be then lowered by the weight of the said plate, means for freeing the plate from the curtain ledge when the curtain reaches the termination of its doWn-. ward travel, and means for then raising the curtain to its normal position.

5. An advertising machine comprising a casin having a display aperture, a plural-* ity of advertising plates arranged one behind the other behind said aperture, supports for said plates adapted to maintaln them slightly inclined backwardly, a forwardly and downwardly inclined chute at the upper end of said supports, means of raising said plates one at a time to a height at which they will overbalance and fall on said chute, a curtain hung above said aperture having a projecting ledge at its lower edge adapted to receive the lower edge of a plate as it drops fr the chute, said ourtain being adapted-.0 be then lowered by the weight of the said plate, means for'freeing the plate from the curtain at the termination of its downward travel, counterof said cards to move the closure member across the opening during the'period of changing the cards.
